ALLEN A. YATES, OF LAKE BENTON, MINNESOTA.

WINDMILL-COUPLING.

Application filed February 13, 1912.

T0 alZ whom, 'it may concern:

Be it known that I, ALLEN A. YATES, a citizen of the United States,residing at Lake Benton, county of Benton, and State of Minnesota, haveinvented a new and useful IVindmill-Coupling, of which the following isa specification.

This invention relates to sucker rod couplers and has special referenceto a spring coupler for devices of this description.

The principal object of the invention is to provide a spring coupler ofimproved construction especially adapted for coupling the sucker rod ofa pump to a Wind niill rod.

Vith the above and other objects in view the invention consists ingeneral of certain novel constructions, combinations, and arrangementsof parts, as will be hereinafter fully described, illustrated in theaccompanying drawings, and specifically claimed.

In the drawing :Figure 1 is a front view of a coupling constructed inaccordance with this invention. Fig. 2 is a side view thereof. Fig. 3 isa side elevation of a portion of the lower end of the main member of thecoupling.

In the construction of this coupling there is employed a main member 10having slots 11 therein wherethrough pass bolts 12 and 13, which boltsare respectively screwed into and pass through a sliding member 1 1. Thebolt 13 is extended through the member 14 and carries an arm 15 which isprovided at one end with a hook 163, the body of the arm having at itsopposite end an offset portion 17 wherethrough the bolt 13 passes andthe end of this oifset portion is bentdownwardly as at 18 to bearagainst the member 10 and frictionally engage therewith.

On the bolt 13 is a nut 19 and washer 20 and between the washer and theoffset portion 17 is a coil spring 21 which serves to yieldably hold themember 15 in position. Secured to the hook end of the member 15 is ahandle 22 by means of which the member can be revolved around the bolt13 as a pivot. Passing through the member let is a pin 28 which is fixedin this part and the Specification of Letters Patent.

Serial No. 677,393.

hook 16 engages the outer end of the pin so that when the hook isdisengaged the pin may pass through a sucker rod and the hook thenengaged to hold the pin in position.

On the member 14 are formed inverted hooks 24: for purpose hereinafterto be described. The upper end of the device is provided with suitableopenings to receive bolts 26 by means of which the device may beattached to the wind mill rod. Secured to the upper extremity of one ofthe bolts 26 is a plate 27 and through this plate and the member 10passes a bolt 28.

Between the plate 27 and member 10 is pivoted a slot hanger 29 throughwhich passes an equalizer bar 80 held fixed in said hanger in adjustedposition by means of a set screw 31. At one end of this hanger there issecured an eye bolt 32 to which is connected one end of a coil spring33, the other end of said spring being connected to one of the invertedhooks 24. T o the other end of the equalizer 30 is connected one end ofa link 35, the remaining end being connected to the remaining hook 24:.

WVhen this device is connected by means of bolts 26 and pin 23 to thewind mill sucker rod, the upward movement of the wind mill rod will betaken up and the shock relieved by the yielding of the spring 33, and itis to be noted that by adjusting the equalizer 80 the force requiredwill be made greater or less according as the spring is moved outwardfrom or in toward the member 10.

There has thus been provided a simple and efficient device of the kinddescribed, and for the purpose specified.

Having thus described the invention, what is claimed as new, is

In a device of the kind described, a mem ber adapted for connection to awind mill. rod, a second member slidable on the first member, a pincarried by the second member for connecting said member to a sucker rod,a hook mounted on the second member and pivoted with reference thereto,said hook being engageable with said pin to form a keeper for the suckerrod, a slotted hanger necting the remaining hook With the repivoted tothe first member, an equalizer maining end of the equalizer lever. 10lever passing through said hanger, a set Dated Lake Bentofi, Minnesota,January screw for holding said equalizing lever in 17th, A.
